Impeller-type spray head of novel electrostatic sprayer

Abstract

The invention relates to an impeller-type spray head of a novel electrostatic sprayer, comprising a motor and an impeller rotatably connected with a rotating shaft of the motor. The impeller comprises a profile and a base which are coaxially arranged, and a plurality of fan blades evenly distributed between the profile and the base along a circumference direction; a motor base of the impeller-type spray head is provided with a liquid inlet and a liquid outlet; when the motor of the impeller-type spray head drives the impeller to rotate, liquid medicine is sprayed out of the liquid outlet through the liquid inlet by means of the spray gun from the liquid medicine tank; the highly-rotated fan blades break the liquid medicine into tiny fogdrops with charge, most of fogdrops are blown forward from clearances among the fan blades, and small part of fogdrops are thrown out along a diversion trench on the inner surface of the profile on the edge of the impeller. Compared with the rotary spray head in the prior art, the impeller-type spray head has larger amount of sprayed medicine liquid flow and favorable atomization effect, and can more deeply spray the fogdrops inside the target as force blowing forward is generated to the fogdrops.

Description

technical field [0001] The invention relates to a novel spray head of an electrostatic sprayer, in particular to an impeller-type spray head of the electrostatic sprayer. Background technique [0002] When the electrostatic sprayer is used for mist spraying, a high-voltage electrostatic generator is used to form a high-voltage electrostatic field between the nozzle and the target. The liquid medicine is atomized into charged droplets through the nozzle. Under the action of the electrostatic field force and other external forces, the fog The droplets do directional movement and are adsorbed on the target, thereby improving the deposition rate of the droplet group on the target. [0003] In the prior art, the spray head of the electrostatic sprayer is usually a direct injection type, that is, a direct injection type, or a rotary disc spray type, that is, a rotary disc spray head. The direct-injection nozzles obtain different atomization effects with different swirl sheet shap...

AI Technical Summary

Problems solved by technology

However, since the turntable nozzle sprays in a small amount, the flow rate is small, the droplets fall naturally, and the penetrating power is weak. For relatively tall or dense spraying objects, it is impossible to spray deeply into the inside of the target object, which affects the spraying effect.
